256 MB x 2 for Wallstreet. options?

I'm shopping for 2 x 256 chips for my Wallstreet II/266. I'm a bit
bewildered by stuff like whether not all of these are 100% OS X
compatible on my WallStreet II. I've seen chips twice as expensive as

What does "Apple certified" mean in this context and why should I pay
double for that? I'd expect all shipping chips to be OS X compatible,
but maybe there can be some differences? What are they?

After all I remember the debacle from this spring when Apple changed
something in an update of whatever it was. But what makes a chip more
compatible than another and how does it actually make the Powerbook more
useful? Hardly the other chips crash several times a day with OS X. Or
do they?

Anyone bought these from Otherworld Computing and run on OS X?:

168L>. OWT say these are OS X compatible. So why would I expect them not
to be?

Anyone bought these made by KTI and Transcend respectively from MemoryX
and run it on OS X?

Can it be unwise mixing makers of chips like that?

Also what is "HyperSpeed Memory":
- p/n MLH6664U/256/KWL from
<http://www.18004memory.com/category.asp?catid=9&subcatid=910>

I've never heard of these kind of chip differences before and what
difference they could make.

512 in mine works fine but I believe that the lower 256 low profile must be
of high quality, not important as all these have life guarantee, keep the
original in case like me you have to send it back for replacement

for the lower one, low profile, Rocky Mountain Ram, because I read that this
company is recommended by Apple

for the high profile, can't remember, any company you see on RamWatch on

no, can't remember, goes back a few years, but I did find on an Apple site
names of ram manufacturers that test and even make ram for Apple, I think
RMram normally sells to stores and companies, but they will sell to
individuals, maybe their ram is not better, but if you look at their site I
think they explain their testing process... quite impressive

I later found that Rocky Mountain Ram can be ordered from
<http://www.devdepot.com>. As the chips are custombuilt for your model,
there seem to be some waiting involved. But I'm assuming this also
assures full compatibility. Also, their shipping $17 to Europe was quite
acceptable compared to others like Other World Computing for instance.
